Mavavu ochulukirachulukira aku China amatumizidwa kumayiko osiyanasiyana padziko lonse lapansi, ndiyeno makasitomala ambiri akunja samamvetsetsa tanthauzo la nambala ya valve yaku China, lero tikutengerani kumvetsetsa, chiyembekezo chingathandize makasitomala athu.
Ku China, mitundu ya mavavu ndi zida zochulukirachulukira, kukonzekera kwa ma valve kumakhala kovuta kwambiri;Mitundu ya ma valve nthawi zambiri imayenera kuwonetsa mtundu wa valavu, mawonekedwe oyendetsa, mawonekedwe olumikizira, mawonekedwe ake, kukakamiza mwadzina, zida zosindikizira, zida zamagulu a valve ndi zinthu zina.Valve chitsanzo standardization wa valavu kamangidwe, kusankha, kugawa, amapereka njira yabwino kulola owerenga kuyang'ana nameplate adzadziwa dongosolo la mtundu winawake wa valavu, zipangizo ndi mbali.
Tsopano tiyeni titenge chitsanzo:

Ntchito yozindikiritsa ma valve
Chizindikiritso cha valavu chifukwa cha kusowa kwa zojambula za valve, kutayika kwa nameplate ndi ma valve sikukwanira, kugwiritsa ntchito moyenera ma valve, ma valve otsekemera, kukonza ndi kusintha mbali za valve ndizofunikira.Tsopano chizindikiro cha ma valve, chizindikiritso cha zinthu ndi chizindikiritso cha valve zafotokozedwa pansipa:
Kugwiritsa ntchito "chidziwitso choyambirira cha valavu" chidziwitso chophunzira, malinga ndi dzina la dzina ndi chizindikiro pa valve ndi valavu pamtundu wa utoto.Mutha kuzindikira mwachindunji gulu la valavu, mawonekedwe omangika, zakuthupi, m'mimba mwake mwadzina, kukakamiza kwadzina (kapena kupanikizika kogwira ntchito), media yosinthika, kutentha ndi njira yotseka.
1.Dzinali limayikidwa pamutu wa valve kapena pamanja.Zomwe zili pa nameplate ndizokwanira kwambiri ndipo zimasonyeza zofunikira za valve.Malinga ndi wopanga pa nameplate, kwa wopanga valavu kuvala zigawo zojambula ndi zambiri;malinga ndi tsiku la fakitale lofotokoza za kukonza;malinga ndi nameplate amapereka zikhalidwe ntchito, kudziwa m'malo gaskets, valavu mbale zipangizo ndi mafomu komanso kudziwa m'malo mbali zina valavu zinthu.
2.Kuyika chizindikiro kumagwiritsidwa ntchito kuponya, kulemba zilembo ndi njira zina m'thupi la valavu zomwe zimawonetsa kuthamanga kwadzina kwa valve, kuthamanga kwa ntchito, mawonekedwe odziwika bwino komanso njira yolowera pakati.
3.Vavu pali mtundu wolembera malangizo otseguka, watsegula sikelo yolamulira kapena kuwonetsa kutsegulira ndi kutseka kwa muvi.Ma valve a Throttle, ma valve a chipata chamdima amalembedwa ndi malangizo osinthira kumapeto kwa gudumu lamanja amalembedwa ndi muvi wolozera komwe kutseka kotseguka.
